You can make your own stickers and magnets. The magnets are safe to be used around computers because they are so thin. But they do stick to fridges and other metal surfaces!
The great thing about doing them yourself is that you can make them anyway you want! You can buy them at any business supply store like Staples and even Walmart has some. You can get "flat" or "glossy" so the look is endless!
Make your design and print out a sample sheet to make sure its the size you want. Now you're ready to feed the sticker paper or magnet sheet and print as many copies as you'd like. When they come out, cut them out.
I have stickers to place inside the cover of my book. This way, the reader can have a special place to place his or her name. "This book belongs to....." And I used a part of the cover so it matches.
These can be used to pass around to people to share your website. You can also use them as gifts during a book signing. The ideas are endless how to use them. Have fun!
